I want to provide Internet access (IP traffic) over LoRa (I know about the airtime limitations). I have two RaspberryPis, with a LoRa hat. One has a WiFi access point (wlan0) the other one is connected to ethernet (eth0).
Hats are configured in point-to-point mode with tncattach:
sudo tncattach /dev/ttyS0 115200 -e -d --noipv6 --noup --mtu 236
ifconfig tnc0 10.0.0.1 pointopoint 10.0.0.2
and on the other one
ifconfig tnc0 10.0.0.2 pointopoint 10.0.0.1
Pings are possible.
Now on RaspberryPi1 I followed this tutorial routing the traffic of the WiFi (wlan0) to tncattach (tnc0).
My question now is, how do I bridge RaspberryPi2's tnc0 to eth0, to provide internet to RaspberryPi1?
